Processing
Bonding only on dry, grease-free, clean substrates. Press the surface well. The material is easy to punch and cut. You can easily adjust the material and cut it to size with a sharp knife.
Cleaning
- No significant soiling from the material is to be expected. In the case of self-adhesive parts, adhesive residues can be removed with a petrol-based cleaning agent if necessary. The safety instructions for the cleaning agent used must be observed.
Delivery form
- Blockware
- Sheet goods
- Cuts
- Punched parts (dimensions on request)
Notes
The material tends to change dimensions during processing (punching, cutting, pressing, winding, installation, etc.). In general, the dimensional tolerances of DIN 7715-P3 can be adhered to. For special dimensional accuracy requirements, please contact our customer service department.
